Tèrchu, or “treasured water' is sourced from a pristine spring in the Himalayan Kingdom of Bhutan.
The spring water source is located at Dolpani, Dekiling Gewog, in Gelephu, at an elevation of 772 meters above sea level in a hilly region with undulating terrain. The spring water emerges at a fracture in the rock formation from an underground aquifer. Geological studies carried out around the spring water source show that the major rock types present in the area are dolomite with siliceous intercalations.
The measurements at the Dolpani spring water source indicate that the average water flow at the source is about 60,000 liters per hour with a catchment area of approximately 13 km2 at an annual rainfall of about 4.9 meters. Carbon dating shows the age of the water at approximately 4,200 years.
With a pH of 7.6 and a harmonious mineral composition abundant in calcium and magnesium, Tèrchu is the ultimate choice for hydration and experience.
Bhutan is often symbolized by the majestic Thunder Dragon, representing its rich heritage and spirit, and it now shares the bottle of Tèrchu as a symbol of the waters' origin.
